Why won't it have a clue?

"Four eights" is a huge pool of public resolvers. "Free" to use (in a
Google sense of a word).

An unnamed consumer-grade router will happily pass DNS requests to
anywhere. Unless it's been tinkered with, which is outside of scope of
this problem.

ISP, of course can:

1) Pass DNS request along, as good ISP should.

2) Route DNS queries to *their* DNS servers. Whenever IPS is abided by
law to do so or merely tries to hijack NXDOMAIN answers to raise some
profit is hardly relevant to the issue.

3) Block DNS requests unless it is going to *their* DNS. Best thing that
can be done about this kind of ISP is contract termination.
